Resistance exercise training has recently been considered as an effective type of training to increase energy metabolism and insulin sensitivity. However, mechanisms of the resistance training-induced improvements in energy metabolism and insulin sensitivity have not been fully understood. Zinc-α2-glycoprotein (ZAG), which is a novel adipokine, has beneficial effects on energy metabolism and insulin sensitivity.
We investigated the effect of a single bout of resistance exercise on the ZAG concentration.
Nine healthy men were enrolled. They performed a single bout of resistance exercise (bench press and leg press) consisting of 10 repetitions of five sets at 70% of maximum strength with 90-s rests in between sets. Blood samples were obtained before and after acute resistance exercise to measure the ZAG concentration.
The serum ZAG concentration significantly increased following acute resistance exercise.
This result suggests that a single bout of resistance exercise may enhance the ZAG concentration.
抗阻训练最近被认为是一种有效增加能量代谢和胰岛素敏感性的训练方式。然而，抗阻训练引起的能量代谢和胰岛素敏感性改善的机制尚未完全阐明。锌-α2-糖蛋白（ZAG）是一种新型的脂肪因子，对能量代谢和胰岛素敏感性有有益的影响。
我们研究了单次抗阻运动对 ZAG 浓度的影响。
纳入 9 名健康男性。他们进行了一次抗阻运动（卧推和腿举），包括 10 次 5 组，每组重复 70%的最大力量，组间休息 90 秒。在急性抗阻运动前后采集血样，以测量 ZAG 浓度。
血清 ZAG 浓度在急性抗阻运动后显著升高。
这一结果表明，单次抗阻运动可能会增加 ZAG 浓度。
